Is a Wi-Fi QR Code Safe? What to Know Before You Share One
Wi-Fi QR codes are convenient, but they also deserve a little thought. The code contains your network name and password, so anyone who can scan it can join your network.
What the code actually contains
A Wi-Fi QR code is simply text in a standard format that includes the network name, the security type and the password. There is no encryption inside the code. If someone photographs it, they have your password.
Where it is fine to display one
- Inside your home, in a private spot
- In a guest room or a rental property for guests only
- Behind the counter or in a staff area, if you do not want public access
Where to be careful
Do not post a Wi-Fi code on social media or in a public window unless it is an open guest network meant for everyone. Photos of codes spread quickly.
Use a guest network
Most routers let you create a separate guest network. Put the QR code for the guest network on display and keep your main network password private. Guests then cannot reach your computers, printers or smart devices.
Good habits
- Use a strong WPA2 or WPA3 password with at least 12 characters.
- Change the password if you think it has spread, then make a new code.
- Avoid WEP, which is outdated and weak.
- Do not reuse the Wi-Fi password anywhere else.
Is QRIQO safe for this?
The QRIQO Wi-Fi tool builds the code in your browser, and the password is not uploaded to a server. If you use the Recent QR Codes history on a shared computer, turn saving off or clear it afterwards, because history is stored on that device.
